Many transportation departments have significant practical experience with bridge preservation and have developed conclusions regarding the effectiveness of bridge preservation actions based on those experiences. However, limited efforts have been made to identify, measure, evaluate, and document the short- and long-term performance of specific bridge preservation actions.

The TRB National Cooperative Highway Research Program's NCHRP Research Report 950: Proposed AASHTO Guides for Bridge Preservation Actions presents the development of two AASHTO guides for bridge preservation, including a general guide to preservation of highway bridges and a guide to preservation of highway bridge decks.

Supplementary to the report is Appendix B: Summaries of Information from State DOTs.
